It's just that nobody has written code yet to do anything with the returned
bitmap handle. However, you can still do screen captures without it.
The below code should also work with just about any window handle,
not just the desktop

import win32gui, win32ui, win32con
hwnd=win32gui.GetDesktopWindow()
l,t,r,b=win32gui.GetWindowRect(hwnd)
h=b-t
w=r-l
hDC = win32gui.GetWindowDC(hwnd)
myDC=win32ui.CreateDCFromHandle(hDC)
newDC=myDC.CreateCompatibleDC()

myBitMap = win32ui.CreateBitmap()
myBitMap.CreateCompatibleBitmap(myDC, w, h)

newDC.SelectObject(myBitMap)
newDC.BitBlt((0,0),(w, h) , myDC, (0,0), win32con.SRCCOPY)
myBitMap.Paint(newDC)
myBitMap.SaveBitmapFile(newDC,'c:\\tmp.bmp')
